Frequently Asked Questions
1What is the standard signature size for SSC, IBPS, and SBI forms?
The standard signature size for SSC (CGL, CHSL, MTS, GD), IBPS (PO, Clerk, RRB), and SBI (PO, Clerk) forms is 140×60 pixels in JPEG format with a file size between 10 KB and 20 KB. Our SSC and IBPS/SBI presets auto-fill these exact values. Sign on white paper in black or blue ink, photograph it, and use this tool to resize.
2How should I prepare my signature for government job applications?
Follow these steps: (1) Sign on plain white A4 paper using a black or blue ballpoint pen. Your full signature should be clear and consistent. (2) Photograph or scan the signature in good light — avoid shadows. (3) Crop the image to include only the signature with a small white border. (4) Upload to this resizer tool and select your portal preset. (5) Download and upload to the form. The signature must be your actual signature — not a printed name.
3Can I use the same signature for multiple exam forms?
Yes, you can use the same resized signature image across multiple forms, provided the dimensions and file size meet each portal's requirements. However, dimensions differ — SSC needs 140×60px while Railway needs 200×80px. Use the appropriate preset for each portal to ensure compliance.
4My signature file is 25 KB. How do I reduce it to 10–20 KB?
Upload your signature to this tool, select the appropriate portal preset, and click Resize & Compress. The tool uses binary-search JPEG compression — it automatically finds the right quality level to bring the file size within the 10–20 KB range without manual guessing.
5What if my signature is rejected during form submission?
Common rejection reasons: (1) File size outside the allowed range — check the exact KB limits. (2) Wrong format — must be JPEG, not PNG. (3) Dimensions wrong — check the pixel dimensions required. (4) Signature not clearly visible — re-photograph with better lighting. Our tool ensures correct size and format, which are the most common causes of rejection.
6What is the signature size for Railway RRB forms?
Railway RRB (NTPC, ALP, Group D, RPF) forms require a signature of 200×80 pixels in JPEG format with file size between 10 KB and 40 KB. Select the "Railway" preset on this tool to auto-fill these values.
